Doesn't work Rated 3 out of 5 stars
I'm not sure whey it doesn't work on my PC. I've disabled all other add-ons and IdentFavicon is the only one enabled. There's no Favicon generated for sites without one. I'm using Windows 7, FF 8.0.This review is for a previous version of the add-on (0.3.4.6).
You could try setting the extensions.identfavicon.debug config value to true (in the about:config dialog). Then identfavicon logs its activity in the error console. Please check its output there and post an error report in email. Thanks!
